The Mégane II Owners' Club

Does it always rev itself up or is the problem intermittent ? if it is constantly doing it check this sensor i have circled in the photo (take the engine cover off to get to it ), It somehow was loose on my megane and it also revved itself up to about 3500-4000RPM , Turned it back in and then it was...

i dont think it can be a problem with the battery if its producing 12 Volts.
Maybe try put the key in the ignition and start the car while the alarm is going off?
might go away... unless your key card has stopped working. Also check the battery in the key.

hope that helps!

i dont think there is any issue if u leave the battery out for a long time.
I bought a megane that had been standing with no battery for about 8 months and all was fine .
Put in a new battery and it started up with no issues

I dont think you should drive it like that ,
Sounds to me like maybe the oil pump failing or a broken valve spring
if its the oil pump and you run it , it could damage bearings, crankshaft and conrods which is a very expensive fix.

The noise is coming from the rear calipers.
Normally the pre 2005 meganes do the noise when braking while reversing and the meganes built during or after 2005 do not...

well you need to put the card key in the card reader,
Push the start/stop button without pressing in the clutch or brake.
The ignition should now be on and you can open /close roof or use the radio .
to switch it off , remove the key and press the start/stop button.

Yes it is also known as an auxillary belt .
Well all the meganes i have seen have air con so it wont make a difference.
The tensioner is in a bit of a tight position to access but its manageable.

lee00069's question makes me think that many of the inhabitants of this forum know surprisingly little about the gearbox they are using daily. There are many gears in the box, which are permanently meshed and "chewing" oil, even in neutral. Dog clutches and friction cones are used to lock...

the accessory belt it is also known as serpentine or fan belt.
With regard to the gears i am honestly not sure, But maybe take it for a drive and see what it does.

well i have never heard of a turbo making any whining sound if it was alternator bearing it is fixable. Your list seems quite comprehensive so i doubt you missed anything. since you used the hand pump it is probably not a problem with fuel supply. Maybe you can take off the accessory belt. Start it ...

Yes it is definitely possible.

Check the fuse. I had a problem with my megane 1.6 auto sedan was stuck in park. Found one of the fuses was blown,
Changed it and was perfect again .

Strange that the turbo would make that sound . I agree maybe something has partially seized. could be something simple like the altenator bearing..... Did you clean out the intercooler? they tend to get full of oil when the turbo gets damaged. And with regard to starting problem heres a suggestion T...

looks great! all u need now is some recaro seats and when its parked no one would be able to tell the difference :P
ive been thinking of putting the recaro buckets in my megane cc ...

sure no problem but a megane hatch or sedan bumper will fit on the cc .
